Termination w.r.t. Q of the given QTRS could be proven:

(0) QTRS
(1) QTRSRRRProof [EQUIVALENT, 0 ms]
(2) QTRS
(3) RisEmptyProof [EQUIVALENT, 1 ms]
(4) YES


----------------------------------------

(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   minus(minus(x)) -> x
   minux(+(x, y)) -> +(minus(y), minus(x))
   +(minus(x), +(x, y)) -> y
   +(+(x, y), minus(y)) -> x

Q is empty.

----------------------------------------

(1) QTRSRRRProof (EQUIVALENT)
Used ordering:
Knuth-Bendix order [KBO] with precedence:minux_1 > +_2 > minus_1

and weight map:

   minus_1=2
   minux_1=4
   +_2=0

The variable weight is 1With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:

   minus(minus(x)) -> x
   minux(+(x, y)) -> +(minus(y), minus(x))
   +(minus(x), +(x, y)) -> y
   +(+(x, y), minus(y)) -> x




----------------------------------------

(2)
Obligation:
Q restricted rewrite system:
R is empty.
Q is empty.

----------------------------------------

(3) RisEmptyProof (EQUIVALENT)
The TRS R is empty. Hence, termination is trivially proven.
----------------------------------------

(4)
YES
